I've been saying for a while now (elsewhere) that the USA's immigration policy can only be interpreted intelligently one of two ways.
The policy as it has stood for the last few decades has been to make it very difficult for skilled people to immigrate to the country legally, while encouraging millions of un(der)educated Third World peasants to immigrate here illegally and then back-dooring them into citizenship some how.
This only intelligent explanations for this are that the elites are looking to either dilute the citizenship of current citizens, or that they're looking to replace the population almost entirely so as to make it more docile.
Yes, the second explanation is just a more extreme interpretation of the first.
The ruling class* is not homogeneous, and their reasons for wanting to replace the current population aren't homogeneous. But here's a nice quote from some Democratic party insiders making it explicit why they're doing this - to insure their future electoral success.
"When you get into a presidential electorate, it decidedly favors Democrats, and every year it’s going to decidedly favor them more and more,” [James] Carville said. “Demographics don’t do anything but get better for Democrats. Every election becomes less white.”Incidentally one can also catch various politicians speaking with forked tongues on both this issue and education**. Virtually all pols speak of the need to have a highly educated work force to compete in the new global economy. If that's the case, why import millions and millions of ignorant peasants?
* I hesitate to call them a governing class for two reasons: first, not all of them are in the government; second, they do a half-assed job of governing.
** Here's a bonus bit on education. Notice how often Obama speaks of the need to educate more scientists and engineers. In this he is like many pols of both parties. But you can be damned sure his precious daughters won't go into science or engineering. They'll go into law/politics or into finance. You won't find many children of the powerful working their asses off studying mechanics or electrodynamics.
